What is it? It's a location-based, quasi-anonymous message broadcast service. What the heck is that? It's kind of like a geo-tagged message board, in real time. The barrier to entry is very low, as long as you have a GPS-enabled device, or browser. I say it's quasi-anonymous because as soon as I push my most recent code to this server you will be able to set a custom nickname for the duration of your session.
My inspiration for this initially came from me sitting in a traffic jam on the way to work, wishing I could tell what the cause of the slow up was. I was saying to myself, "if I could just ask the people in front of me what the deal is then I'd know how long I'm going to be sitting here." After coming home and coding this, I started thinking more about it and it's a lot like Citizen's Band radio. I go into a lot of that on the about page.
Ok, so what does this do? It simply lets you broadcast a message, in real time, to people around you. Your message will be broadcast to all users within 5 miles of you, all directions. Messages are archived for the location from which they were sent. This means that when you connect, you should see the 5 most recent and closest messages for your current location. If you see none, that just means there have not been any, yet. This also means that messages may be left for future users, too. So, real-time discussion is not the only option.
This does not work in IE, as far as I know. The browser does not support geolocation (?). This works great on my iPhone 4, and updates your location as you move.
